My TV had a double image for about 1 month that disappeared after 10 minutes of operation. After about a month, the picture no longer comes on. Is this the mother board?

Double image is more likely to be the T-CON (TIMING CONTROL FOR THE ROW AND COLUMN SCANNING OF THE LCD PANEL PIXEL).
Can you still see the glow from the TV?
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

Upgraded to Hd and tv started messing up. Double images for first 10 minutes and sometimes tv picture goes off and lines up and down.


Your HDTV is capable of up to 1080P resolution. SDTV (standard def) signals are 480i; EDTV (enhanced def) is 480P; HDTV are 720P, (there is no 720i) 1080i and 1080P. Generally, those modes ending in "P" look better than those ending in "i". 1080i is the highest possible for broadcast TV, but BluRay disks and Directv have 1080P display capabilities.

The double picture you're describing sounds like the TV is set to display only standard or enhanced def signals while the Dish Network box is supplying it with HD signals. You should locate the control for the TV's resolution and make sure it is set to "1080P" and then set the output of your Dish Network set top box to the highest output it offers. Do the same for your BluRay player and any other devices, too.

Once set correctly, you should have a great picture once again. I hope this helps & good luck!

My zenith sentry tv has a double image on the words that come on screen. The people are clear but all wording has double images


Hello
Double images are technically called Ghosts, occures due to the setting and direction on the antena. You have to reorient your antena, in such a way that Ghosts disappeares from your screen. The reson for this fault is not with the TV, as it gets a direct transmission signal, and a reflected signal of the same, reflected from near or far objects, like tall buldings, hills and so on. The signals, the orginal and the reflected, will be processed by the TVs internal ciiruit, and the first will appear as strong picture, followed by the second, a weak picture, will be seemed as an image of the first one, just on the right side [view point] of your TV.
You just adjust the position and height of your antena, looking the picture, where there is minimum Ghost level is. No other repair should be done to your TV, as it is perfect, and you just give it only direct signal path. OK.

TV works fine for a while, then the picture disappears.


I would just replace the TV, the parts are not going to be made to repair this. The set is just to old.

Takes awhile for tv to come on!


Hello Ruben,
This type of failure is common on these TVs. The power supply might need to be replaced due to bulging capacitors. If you are able to replaced the capacitors, it is a cheaper alternative.

Hi im michael i have a old sony projection screen 10 years old or more. i believe its a trinitron.the picture comes on for awhile then goes out and comes back on just a minute later


Hi Michael,

If you were to watch a DVD using a different input than the cable/satellite input, does the image also fade in and out? When the image disappears, are you able to view the TV's onscreen menu or does it disappear too? When the image comes back, does it look fine and is the brightness the same?

Good day.
First, Have your tv 's circuitry be resoldered. this might be a case of loose contacts particularly along the crt circuitry. the longer you operate the unit at this condition, the faster you are counting the possibility of shortening the lifespan of your tube. 9 years is quite a young age for a unit which has an average of 18years.


response is highly appreciated.

When set if first turned on, the stereo/stand-by light (red) flashes on/off until just before picture first appears .if your tv is very old than it might be due to crt getting weak crt base loose loose contact in power supply thanks

Tv has sound but no image


When you say no image this could mean anything from, snow picture, blank screen, blue screen. Also, dry joints on the PCB can cause such a problem. More especially on the picture tube board.
